FLUSHlNGhVALVE.

SPECIFICATION forming part of Letters 'Patent No. 290,256, dated December 18, 1888. Application filed February 12, 1883. (No model.)

To LLZZ whom, t may concern:

Be it known that I, JAMES MCGINLEY, a citizen ofthe United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Flushing-Valves, of which the following is a specification, to wit:

This invention relates to valves for the purpose of iiushing water-closet bowls; and it cons ists in a pair of alternately-closing valves connected to a supply-pipe, a tank or reservoir, and a flushing-pipe, and operated by a system of levers connected with the closetseat, substantially as will be hereinafter-set forth, and pointed out in the claims.

r In order to enable others skilled in the artv to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings,in which* Figure l is a view partly in sectionof my device applied to a water-closet, and Fig. 2 is an enlarged detail of the devices for adjusting the operating-levers and their connections.

Arepresents the bowl of a'water-closct, and A the seat covering the same, which is on its nnder side provided with the usual cup-shaped casting, a, for the reception of the upper end of a rod, B, which extends downward a short distance, and is pivoted at its lower end to a lever, C, fulcrumed in a supporting-standard, c, secured to the floor, and the other end of this lever is pivoted to the lower end of a rod, D, extending up above the seat Al to a suitable height, and pivoted to a lever, E, fulcrumed at one end to the wall, and at the other i connected to a valve-rod, F, as represented in Fig. 1.. This valve-rod extends downward into a small valve-cylinder, F having its upper and lower ends enlarged to receive the valves, and provided with ,two =oppositely faced valve-seats, as shown. The upper enlarged end of this cylinder is closed by a cap,l

j', provided with a suitable stuffing box, through which passes the valve-rod F, and the lower end is secured by a suitable `coupling to the flushing pipe f', connecting with the closet-bowl. To the upper end of the valvecylinder is lconnected the supply-pipe G, leading to the water-mains, and between the' upper and lower valve-seats is connected the pipe G, leading to the flushing-tank G2. The

suitable distance apart, with two oppositelyseating valves, g g', removably secured to the rod, as shown in the drawings.

At any point upon the system of levers between the fulcrum of the lever C and the valvecylinder F is secured a weight, II, which tends to keep the upper or supply valve, g, normally closed and the lower or flushing valve, g', opened.

When the closet is used, the seat isslightly depressed, operating by the intermediate systeni of levers Vto lift the valve-rod, opening the valve g and closing the valve g. rIhe water from the main then enters the cylinder F', and, passing through the pipe G, fills the flushing-tank G2. When the pressure upon the seat is removed, the weight H draws down the valve-rod, closing the valve g and opening the valve g', allowing the water in the tank to flow out and flush the bowl. It will be seen that the valve g is held closed by the weight H and the pressure of water from the supplypipe, and cannot fail to be closely seated, and also that the same amount of water willalways ilow into the bowl for flushing purposes, and none can be wasted by holding down or The tank and flushingpipe f being always emptied after the closet is used, cannot freeze.

In order to compensate for any displacement or wear of the seat by long use, and to adjust one size to different closets, I also provide the upper end of the rod B with a' screwthreaded hole, b, into which is screwed a lengthening-rod, b, which may be screwed in or out and held wherever desired by a locknut, b. It is also necessary, in some cases, to set the bowl farther from or nearer to the wall by reason of the location of the lioor-joist, and in order to provide for this variation I form the rod or lever C in two parts, one of -which telescopes within the other, and is held wherever required by a set-screw, c', as seen in Fig. 2.

Having thus fully described my invention, what I claim as new7 and Vdesire to secure by Letters Patent, is.-

1. In a water-closet having its flushing devices operated by pressure uponthe seat, a

`push-rod,B, provided with the screw-extension b and lock-nut '52, whereby it maybe easlower end of the valve-rod F is provided at `a IOO rod F, provided with two valves adapted to open and close the supply and iushing pipes 15 alternately, the Cylinder IF', supply-pipe G, tank G2, and flushing-pipe f, all combined, constructed, and arranged to operate substantially as and for the purpose set forth.

In testimony whereof I affix my signature in 2o presence of two witnesses.

JAMES MCGIXLEY.
